WHEEL-MOUNTING.

To all whom it may concern: 7

Be it known that I, CHARLES A. BAUMLER, a citizen of the United States, residing in Buffalo, in the county of Erie and State of New York, have invented. new and useful Improvements in Wheel-Mountings, of which the following is a specification. This invention relates to a mounting which is more particularly desi ned for the wheels of toy wagons although tne same may also be used for other purposes.

The objects of this invention areto provide a retainer for the rollers of the bearing which is simple, eflicient and inexpensive; also to improve the means for confining the roller in engagement with the bearing surfaces, and also to provide superior means for retaining the capon the hub of the wheel containing the roller. bearing.

In the accompanying drawings:

Figure 1 is a fragmentary longitudinal section of a wheel equipped with my improvements. Fig. 2 is a cross section of the same taken on line 22, Fig. 1. Figs. 3 and 4 are perspective views of two roller sections and their retainersforming part of my. invention. Fig. 5 is a plan view showing the form of the blank from which one of the roller retainers is constructed. Fig. 6 is an elevation of one end of the'casing of the roller bearing' Fig. 7 is an elevation of the opposite end of the same with some ofthe fastening lugs bent into place and othersin their unbent position. Fig. 8 is a plan view of the front hub section and one form of the cap attached thereto. Fig. 9 is a perspective view of another form of hub cap embodying my invention.

Similar characters of reference refer to like parts throughout the several views.

10 represents the metal axle of a toy wagon or other wheeled vehicle which in this instance is secured to the underside of a wooden bolster llby a rivet 12 or otherwise. Upon the end of this axle is journaled a wheel which may be variously constructed but which, as shown in Figs. 1 and 2, preferably comprises a hub having tubular front and rear sections 13 and 14: which are secured by rivets 15 to the opposite sides of spokes 16. Within the sections of this hub is arranged thecasing 17 of the roller bearing which is of metal and of tubular form. One end of this casing, for example the rear end thereof, as shown in Figs. 1 and 6, is

providedwith'a lfixed head 18 which has the form of an annular flange projecting inwardly from the body of the casing. The opposite end of the casing is provided with a removable head l9.which is preferably constructed in the form'of a ring and which is detachably connected with the casing by means which preferably consists of a plurality of notches 20 formed in the edge of the ring shaped head, and a plurality of lugs 21 arranged at thefront end of the casing and projecting through the notches of the ring shaped head and bent against the outer side of the same. In Fig. 7 the lower'and right hand lugs 21 are thus bent into place while the upper and left hand lugs are still unbent. In order to limit the rearward movement of the casing in the hub the rear section of the latter is provided at-its rear end with an inwardly turned bead or shoulder, 22 which is engaged by the rear end of the casing, as shown in Fig. 1. A washer 23 is preferably interposed between the rear end of the hub and the bolster. The hub is confined on the axle by a cotter pin 24 passingvthrough an opening'in the axlein front of the hub, awasher 25 being preferably arranged on the axle between this pin and the front end of the casing.

The front end of the hub, casing and axle are inclosed by a cap 26 which slips over the hub and is detachably connected therewith by one or more locking lugs 27 preferably bent laterally out of the metal of the hub at'the fr front end thereof and each engaging with a bayonet slot in the adjacent part of the circular body of the cap. This slot preferably comprises an inclined rear inlet portion 28 and a reentrant front portion 29 forming a shoulder 30 between the front and rear portions of this In Figs. 1 and 8 this bayonet slot extends from the bore to the periphery of the hub cap while in Fig.

9 this slot is closed on its outer side by' a cover 31 so that the same only opens toward the inner side of the casing. The rear ends of the slots in the cap are engaged with looking lugs and then the cap is pushed rearwardly whereby a rotary motion is imparted to the hubby the oblique rear parts 28 of the slots. During the last part of this rotary motion of the hub cap the reentrant parts of its slots brings the shoulders 30 thereof into engagement with the locking lugs 27' and thereby holdsthe cap against accidental displaceznent. To secure this result the parts are so proportioned that the rear end oi the cap bears against the base i 32 of the front hubsection andnecessitates springing the cap. slightly in order to engage its shoulder 30. with the lugs'28..

Between the inner side or bore of the bearing casingand the peripheryiof the axle are a" plurality. of bearingrollers 33 whichare arranged parallel and in an annular row sothat the outer sides of the same engage the casing and the inner sides :of the same with the axle.-

For the purpose of enabling these rollers to be easllyinserted into the caslng and retained in theirfproper working position a roller retaining device'is' provided which in its preferred form is constructed in two sections each of which is adapted to 'e'ceive one half o'f all thefirollers, so that the rollone are in effectdivided into two semi-circular rows. or groups.

In its preferred form each of these roller retainers compr1se two longitudinal bars 3ft wlnch'are arranged lengthwise atoppo- {site sides of tlieset of rollers and two cross with a plane arranged radially and transbars 35 which connect the corresponding ends of the longitudinal bars are arranged at opposite ends of the set of rollers/y The longitudinal bars are constructed of flat metal and? so arranged that the flat sides of the same. are parallel Witha'plane arranged lengthwise and radially relatively to" the axis of the bearing, and each of saidcross bars also constructed of flat metal and soarrangedlthathitsfiat sides are parallel versely relatively to the axis of the bearing. Each of the cross barsis curvedcon'centrically with the axis ofthe bearlng, or substantially so,and is provided with a row of pivot openings 37 in which are journaled the trunnions orreduced necks :36 onthe adjacent ends of the rollers 33, as shown inFigs.

1, 3 and 4t. Each of these retainers is prof erably tormed integrally from metalby first stamping a blank of the form shown in Fig. 5, which consists of two longitudinal bars connected at their opposite ends by two curved cross bars, theseseveral bars being all arranged the sarneplane, and the cross bars being provided with the pivot openings. The cross bars are now bent at right angles to thelongitudinalbars and during this bending operation the openings of the cross bars may be engaged 'Wltll the trunnions of the rollers for retaining the latter in parallelism with each other. I in the assembled position oi the parts the longitudinal bars otone roller retainer engage the longitudinal bars of, the other roller retainer so that'the two retainers together form practically a continuous annular re tainer which completely iills the space he tweenthe bearing casing and axle and holds the rollers reliably against displacement.

so A

v This retainer is therefore not only eilicient 1n operatlon but the same is also very having the form of anT'annular flange, and

a removable head detachably connected with the other end of said casing and having the form ofa ring.

2. A. wheelmounting comprising a plu-. rality of rollers arranged parallel and adapted to surround an axle, a cylindricalcasing engaging its inner side with the outer side of said rollers and provided at one end with an integral inwardly projecting head having the forrn of an annular flange, and a removable head detachably connected with the otherfend of said casing and havwing the form of a ring,'said ring shaped head and. the adjacent end-o f the casing being connected by providing said ring shaped head in its edgewith notches and I providing the respective" end of said casing with lugs which engage with said notches and are bent inwardly against the front side of said ring shaped head. i V GHARLESA.
